Allowed Usage-Based Charges
You can include usage-based charges in your product's price. However, not all of the available usage-based charges can be part of your product's price. The following tables show each of the usage-based costs AWS charges for and whether you can include a corresponding charge in the price of your DevPay product. For more information about the usage-based costs, go to the Amazon EC2 detail page and the Amazon S3 detail page.

The list of usage-based costs changes as Amazon EC2 and Amazon S3 release new features. The pricing examples, fee examples, and DevPay Activity page examples presented in this guide might not reflect all the currently available usage-based costs the services have. However, the concepts presented by the examples are still valid. |
